yes, the sound quality of the PRE LP is very good. But the point is: I distinctly hear, when I listen closely, a difference in the vinyl noise in between tracks and the vinyl noise at the very beginning and ending of each track, both in level (it's lower in between tracks) and "colour". The change is sudden and easy to hear, although you have to listen with headphones to notice it. This for me indicates that the tracks are mastered from vinyl. Or how would you explain it?
